“Warning – Your Computer Is Infected” hoax is a technical-support-scam[1] alert, which contains false claims about Trojan infection and possible hard drive failure. It mimics the features of a legitimate Microsoft notification and prompt the PC's user to call one of the two Customer Support numbers.

The Your Computer Is Infected scam is displayed in a form of a full page new tab window. It simulates Microsoft Windows BSOD in the background, a bar-code, and two Windows Service Center contact numbers: +1-877-304-0310 and +1-866-820-7252. To intimidate people and trick them into calling them, crooks render bogus claims about unknown Trojan infection in the hard drive, which can lead to leakage of personal information and complete data loss.

However, dialing this phone number is not a good idea for several reasons:

  • the phone call might be charged more than a regular call;
  • crooks might want to sell you bogus security software;
  • scammers might want you to install remote access tools;[2]
  • criminals might trick personal information about you.

“Warning – Your Computer Is Infected” virus uses Microsoft’s name and credentials to make this scam look like real notification. When users are redirected to the malicious website, it locks the screen and delivers two pop-up windows. The first notification briefly informs about computer infection, provides support phone number and asks whether you want to leave this page or not.

  • blocked firewall,
  • account suspension,
  • leakage of the personal information.
  • infiltration of the Trojan.
  • the possibility of losing a credit card or banking information.

Authors of the “Warning – Your Computer Is Infected” scam claims that trying to find and delete this “virus” manually may lead to data loss and other problems. They want to make users believe that only “certified technicians” can solve this problem.

How to prevent from getting malware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
